In this follow-up to his Agatha, Anthony, and Macavity Award winner Agatha Christie's Secret Notebooks, Christie expert and archivist John Curran once again plumbs the unpublished notebooks of the world's bestselling author to explore the techniques she used to surprise and entertain generations of readers. Curran charts the evolution of more than 20 novels, as well as stage scripts, short stories, and some more personal items. Among these gems are Christie's essay on Hercule Poirot, written for a British newspaper in the 1930s; a previously unseen version of a Miss Marple short story; a courtroom chapter deleted from her debut novel The Mysterious Affair at Styles; and an insightful analysis of her final, unfinished novel, based on Christie's notes and Curran's unsurpassed knowledge of the author and her work.
